Description
Technical field
The present invention relates to a kind of drilling rod, particularly relate to a kind of novel spiral drill rod that can directly drive by unit head key cover.
Background technology
The application of pile foundation construction boring machine aspect basic engineering construction more and more widely.Long spiral worker method is to adopt to have the long-spiral drilling machine of core pipe to carry out drilling construction, and after waiting to reach hole depth, with in the core pipe injection hole of concrete by long screw drill rod that mixes, the limit is carried and bored the limit infusion up to finishing pile then with the high pressure concrete delivery pump.Long spiral worker method adopts dry type rotary drilling, need not mud circulation, avoids useless slurry to pollute; The pore-forming efficiency height; Can avoid undergauge, broken pile, hole wall collapse and shrinkage cavity situation to take place, have low noise, pollution-free, high efficiency and the complete characteristics of pile body, so be widely used.The type of drive of traditional long screw drill rod is to adopt unit head to drive drilling rod, be equipped with on the unit head and have the unit head key cover that drives internal key, unit head key cover matches with the drilling rod of one section no helical blade, and this drilling rod passes to auger stem with moment of torsion again, finishes creeping into of drilling rod.This kind type of drive necessarily requires to connect in the upper end of auger stem the drilling rod of one section no helical blade, unit head also must rise to certain height, this must cause, and the center of gravity of complete machine raises, stability reduces, complete machine move or turning course in cause safety factor to reduce.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure, good stability, safe, lower-cost novel spiral drill rod.
Novel spiral drill rod of the present invention comprises that the two ends of the body of rod, the described body of rod are provided with linkage, some helical blades fixedly are housed on the lateral wall of the body of rod, head and the tail connect between the described helical blade, evenly be provided with some breach on the outer edge of wherein said helical blade, the keyway that constitutes along the axially adjacent some breach of the body of rod axially parallels with the body of rod, and described keyway matches with the driving internal key of unit head key cover.
Novel spiral drill rod of the present invention, wherein said breach is provided with the keyway piece, and described keyway piece coats the edge of breach fully.
Novel spiral drill rod of the present invention, wherein said continuous three straightness accuracys along two relative medial surfaces of the axial keyway piece of the body of rod arbitrarily all are not more than 2mm.
Novel spiral drill rod of the present invention, wherein said keyway circumferentially evenly is distributed as 3 along helical blade.
Novel spiral drill rod of the present invention, wherein said linkage comprises outer six square joints, interior six square joints and is connected bearing pin, described outer six square joints and interior six square joints are separately positioned on the two ends of the body of rod and cooperatively interact, the lateral wall of six square joints is provided with pin shaft hole in described, the lateral wall of described outer six square joints is provided with the groove of arc section, in six square joints time, groove and pin shaft hole coincide, and the connection bearing pin matches with pin shaft hole in outer six square joints insert.
Novel spiral drill rod of the present invention, the middle part of wherein said connection bearing pin is provided with annular groove, and the lateral wall of described interior six square joints is provided with the screwed hole perpendicular to pin shaft hole, and described screwed hole is communicated with pin shaft hole, is provided with screw in the screwed hole.
Novel spiral drill rod difference from prior art of the present invention is evenly to be provided with breach on the helical blade of novel spiral drill rod of the present invention, breach along the drilling rod axial distribution constitutes the several keys groove, keyway matches with the internal key of unit head key cover, make unit head key cover directly to drive auger stem and creep into work, do not match with unit head key cover and need not connect one section drilling rod in the upper end of auger stem, compare with traditional auger stem, the center of gravity of novel spiral drill rod of the present invention is lower, creep into moving process in good stability, safety is higher, and cost also decreases relatively.
The keyway piece is housed on the breach in the novel spiral drill rod of the present invention, is to prevent stress deformation for the edge of protecting breach; The two relative medial surfaces straightness accuracy in the axial direction that guarantees the keyway piece is not more than 2mm, be when making unit head drive auger stem, the driving internal key of unit head key cover and the cooperation of keyway are tightr, helical blade stressed more even, and the slip that the unit head key is enclosed within on the auger stem is more smooth and easy; Interior six square joints that install at body of rod two ends are to be connected easier for the lengthening that makes auger stem with outer six square joints.
Below in conjunction with accompanying drawing novel spiral drill rod of the present invention is described further.
